To aZZ whom it may concern:

Be it known that I, HERBERT O. WARREN, a

citizen of the United States,"res idin'g at Hartford, in the county of I-Iartfordfand State of Connecticut, have inventedoertain; new and; useful Improvements in Universal Joints, of.

which the followingis a specification.

My invention relates-to universal jointfsg;

and ithas for its object the .provision of a deviceof this character simple-and strong in construction and composed of but fewparts which can be cheaply mauufacturedand may be readily assembled with a minimum expenditure of time and-labor.

A further object of the inventionis the provision in a universal joint of blocks of peculiar construction and connected to the ends of the shafting in a distinctiveway, all as will be hereinafter described.

In the accompanying drawings, Figure 1 is. a side elevation of my improved universal joint. Fig. 2'isa similar view with the ends of the shaft ing and with the uniting-blocks in section. Fig. 3 is a sectional view taken on the line of the pin for securing the rocking blocks in position, said blocks and the bifurcated end of one oftheshafts being in section; and Fig. 4: is a plan-view of the inner side of one of the blocks. 7

Like numerals designate similar parts throughout the severalviews.

Referring to the drawings, the numeral 5 designates a shaft provided atfits' ends with arms 5 5 and with a concavity 5 and the numeral 6 another shaft having arms 6 6 and a concavity 6 These arms and the concavity may be formed on the ends of the shafts in any desired mannerfor instance, by removing the metal or by casting, if desired. Inwardly projecting from the arms 5 5 are headed studs 7 7 as illustrated in Fig. 3, and

the shanks or barrels of these studs are shown.

by dotted lines 8 8 inFig. 3 as passing through said arms;-but other modes of attachment may be adopted, if desired. The arms 6 6 of shaft 6 are perforated at 9 9', respectively, for the reception of a bolt 10, hereinafter described, said bolt being threaded at 10 at one of its ends-to enter a nut formed in the arm 6 as illustrated in Fig. 2.,

Designated by the numerals" 12 12' are blocks, and these blocks are provided on their inner faceskvithisemicircular grooves 13 and lar. grooves and 16, respectively. Each block is also perforated at 17 for a purpose hereinafter set forth and isiprovidedwith shallow passages or, grooves.18,iwhich may be arranged-in jany desired'mannergfor the re- "ception of oil or otherlubricant. The heads 'of the studs or pins 7 7 are designated, respectively, by the numerals and 20 and are of a conformation suitable to be received in the semicircular grooves 13 and 14 of the blocks, the shanks of said studs fitting in the shallow grooves 15 and 16, as illustrated in 3.. .The two. sections 12 and- 1'2iconstitute, when placed upon the studs in the mannerdescribed and as illustrated in Fig. 3, a connecting-block, and in order to assemblethepartsof thejointthese sections are first 'fittedover theheaded studs. The furcated end of, the shaft 6 v isitlienplaced in position over .saidconne'cting-blockuntil the perforations 9 9 of the arms 6 6 are in line with the central opening 17 of said block, and the bolt 10 is then passed through the alined, openings in the arms and connecting-block and bears against the faces of the heads 20 20' of studs 7 7,, andsaidboltis then turned to cause its threaded end to engage with the threaded walls or-nut of said opening 9, as illustrated inFig. 2. This construction provides a very simple and convenient joint, one that can be readily.andcheaply manufactured, and Whichwillbeeasyin operation and effective for all of the purposes for which said joints are usually employed;

To permit the rocking or turning movement of the connecting-block, the concavitieso t tions to turn upon said block the arms 6 6 of shaft 6 swing upon the bolt 10 and the arms 5 5 carrying the headed studs7 7, swing upon the connecting-block;said'studs readily rocking within the grooves 13, 14., 15, and 16 of said block. In this way by a simple and cheap construction composed of few parts and capable of being manufactured by machinery or by casting a universal j ointis provided the parts of which may be readily assembled and disassembled and which will per- -l%l, respectively, and with shallow semicircuare provided, and to enable the shaft-secrmit the shafts united by said joint to be moved with ease and facility in any desired direction.

As will be observed by reference to Figs. 1 and 3, the parts of my improved universal joint are all looked together, and inasmuch as the surface or periphery of the bolt bears against the heads 20 and as said bolt passes through both the arms 6' 6 of shaft 6 and the sections of the block a compact construction is provided, one which will not yield when end thrust is applied to either of the shaft-sections and which will readily and easily conform to the motion or position of either of said shaft-sections.

My invention is not limited to the precise details of construction illustrated and described, to the form of the sections of the'connecting-block, nor to the specific grooves and studs described for uniting said block with the shaft, for many changes may be made therein without departure from the invention.

Having thus described my invention, what I claim, and desire to obtain by Letters Patent, is

1. In a universal joint, the combination,

' with a furcated shaft having headed studs, of a sectional connecting-block having grooves for the reception of the heads of said studs; a second shaft; and means for uniting said second shaft to said connecting-block.

2. In a universal joint, the combination, withashafthavinginwardly-projecting arms, of headed studs carried by said arms; a sectional connecting-block fitted to said studs,

"each section being grooved to receive the with a shaft having arms at its end, of headed studs carried by said arms; a sectional connecting-block having grooves for the reception of said studs,each section of said block being perforated; a second shaft having perforated arms; and a bolt for securing said shaft to the connecting-block, said bolt passing through the alined perforations of the connecting-blocks.

5. In a universal joint, the combination,

with a shaft having arms, of headed studs carried by said arms; a sectional connectingblock having grooves for the reception of said headed studs, each of the sections of said block being perforated; a second shaft having perforated arms; and means passing, through the perforations of said arms and block for securing the parts together.

-6. In a universal joint, the combination, with a shaft having arms, of headed studs carried by said arms; a sectional connectingblock, the sections of said block having grooves for the reception of the headed studs and being perforated; a second shaft having perforated arms, one of which is threaded; and a bolt having a thread at one of its ends for engaging with said threaded arm, said bolt passing through the perforations of the sectional connecting-block and serving to unite the parts, substantially as set forth.

7. In a universal joint, the combination, with a shaft concavedat its end and having arms, of laterally-projecting, headed studs carried by said arms; a sectional connectingblock, each section of the block having grooves for the reception of the studs and also having lubricating passages, and each of said sections being perforated; a second shaft concaved at its end and having perforated arms, one of said arms being internally threaded; and a bolt having a screw-thread at its end, and serving to unite said shaft with the conmeeting-block.

8. The combination, with devices having furoated ends,'of studs, each having a projection, carried by one of said devices; a sectional block, each section of which is shaped to receive the studs and is also perforated; and a bolt passing through one of the furcated devices and through the sectional block, said bolt bearing against the projections of the studs.

9. The combination, with devices,each having a pair of arms, one pair of said arms being perforated, of devices extending laterally from the other pair of said arms, saiddevices having projections; a sectional block having grooves to receive the projections, each section of said block being perforated; and a bolt passing through the perforations of the arms and block-sections and bearing against said projections.

In testimony whereof I aflix my signature in presence of two witnesses.
